T0 all,wh0m it may concern:

Be it known that I, ALGERNON K.,JOHN- STON, of the city, county, and State of New York, have invented a new and useful piece of Apparatus, called a Pholophene-Box, for use in Garbureting Gas; and I here declare that the following is a full and exact description thereof, reference being had to the accompanying drawings.

I first provide a box, of which Figure l is a longitudinal vertical section, and Fig. 2 a transverse vertical section in the line as x of Fig. 1.

I prefer to have the box of metal. Across the top I extend wires, strips of metal, wood, or even twine, c, or place the shavings on shelves or grating. Across these I hang shavings d d, so that they shall extend from the top to near the bottom of the box, or perhaps to the bottom. I now partially fill the box vide nearly the same amount of evaporating.

surface as will shavings.

What I claim as my invention is The use of the materials above described, for the purpose set forth.
